If you have a big budget stroke it to 331-347 and run a good set of AFR heads.
If your looking for bang for the buck I would bore it .030" and use a set of Speed Pro flat tops. Stock cast heads will make good power, but if you get into swapping larger valves and mild porting, it would be just as easy to go with a set of after market heads. Cam choice is also pretty important. Your block is designed for flat tappet hydraulic cams. If you keep the duration around 220* or less and the lift less than .550" it should be very streetable and easy on the valve train. Comp Cams makes several different grinds, FRPP and Summit brands are several that I've used and been pleased with.
Get an idea of what you want and I can run the #'s through my Desktop Dyno to give you an idea of your final product.
